Survey readout

Lyman Lake is mapped to a depth of 30 ft on the Michigan DNR survey and covers about 74 acres in Delta County, Michigan.

Measured from the Michigan DNR inland-lake contour survey.

Deepest mapped contour: 30 ft
Mean depth: 8.7 ft · estimated
Surface area: 74 acres
Estimated volume: 645 acre-ft · 210M gal
Shoreline: 2.01 mi · irregular
Aquatic vegetation: 0% of surface · NDVI estimate
Public access: Boat Launch

Additional depth details5 contours

Contour depths: 0–30 ft
Recorded point soundings: 30 ft

Other waters with a public launch on this map: Gooseneck Lake. Their launches are not marked on the model — only Lyman Lake’s own are.

62.8% of the surface sits over water shallower than 10 ft; 7% is deeper than 20 ft. Depth, area and volume are estimated from the interpolated survey surface — historical reference, not measurement.

Paddling

Paddling Index methodology v1.0 · calculated 2026-08-21

80 / 100Very GoodData confidence: Medium

Lyman Lake has a mostly natural, lightly developed setting, well sheltered geometry, little nearby major-road exposure. No special watercraft restriction is identified in the current source.

Why this score?5 components

Included in the index

Component	Rating	Points of weight	Measurement
Natural setting	Very Good	26.9 of 35	79% natural land cover within 150 m of shore (63% forest, 14% wetland; 13% developed)
Geometric wind exposure	Excellent	26.5 of 29	mean fetch 557 m · 37% of sampled water within 500 m of shelter · short fetch in most directions
Watercraft controls	None identified	8.8 of 18	No special watercraft restriction identified in the current DNR source. Motors permitted, subject to general law.
Public access	Not listed	—	No DNR-listed access site. Township, county and road-end launches are not in this source, so this is not evidence that access is poor — the component is excluded and the remaining weights are renormalized.
Road isolation	Excellent	17.6 of 18	relatively isolated from major roads · 7 MDOT-classified segments within 1.2 km, peak 33 vehicles/day

Additional paddling considerations

These describe the lake but are not part of the v1 Paddling Index and do not change the number above.

Wake sensitivity: Low — wide enough that wakes disperse over most of the lake
Aquatic vegetation: Low — approximately 0% mapped coverage · NAIP aerial imagery (NDVI)
Observed motorized activity: Unknown — No lake-level measurement of boat traffic is available. Legal permission to operate motors is not evidence of use.
Wildlife habitat potential: High — 63% forest and 14% wetland cover within 150 m of shore

Compare Michigan lakes by Paddling Index →

How this index is calculated. The Paddling Index is a relative composite derived from lake geometry and public environmental, access, roadway and watercraft-control data. It is not a user review, a safety rating, or a prediction of an individual outing. Differences of a few points should not be treated as meaningful — an 84 and an 82 are broadly comparable. Components and weights: natural setting 30%, geometric wind exposure 25%, watercraft controls 15%, public access 15%, road isolation 15%; observed motorboat activity is weighted 0% because no defensible lake-level measurement exists. Where a component has no data the remaining weights are renormalized and the confidence rating is lowered; below Medium confidence no number is shown. Sources: MI DNR Watercraft Control Areas (2026-08), USGS/MRLC NLCD Land Cover (2021), MDOT Annual Average Daily Traffic (2025) and MI DNR bathymetric survey outline (0 ft isobath). Conditions change quickly — check current weather and local conditions before going out.

Fish you might catch

Fishing rules for this lake Beta

Size and daily limits for the 2 species found here — 1 open to harvest, 1 with a special rule or closed season.

These are hook-and-line size, daily limit and season rules. Gear, spearing and bow fishing, spawning closures and rod limits are set by other Fisheries Orders and are not shown here.

Redhorse SuckerSpecial rulesMost redhorse suckers have no size limit, no possession limit and are open all year. River Redhorse is state-protected and may not be taken.

BluegillOpen to harvestMinimum size: no size limit · Daily limit: 25 (FO-215 · statewide inland) The 25 is in any combination of the sunfishes — Bluegill, Pumpkinseed, Black and White Crappie, Rock Bass, Green, Longear and Redear Sunfish, Warmouth and hybrids — not 25 of each (FO-215.23A).

Beta. This panel is newly published. Every value is parsed from the Michigan DNR fisheries orders and hand-checked against the printed digest, but the coverage and wording are still under review. If anything here disagrees with the Michigan DNR's Fisheries Orders or its printed digest, the DNR is right — the signed Fisheries Order is the legal text; the digest summarises it.

Redhorse SuckerSpecial rulesMost redhorse suckers have no size limit, no possession limit and are open all year. River Redhorse is state-protected and may not be taken.

Notable catches

Master Angler program · 1998–2025

Master Angler catches recorded on this lake — too few to show a pattern, so they are listed individually.

Bluegill10.1″ · 2009 · spincasting · leech

Bluegill10″ · 2025 · still fishing · live bait

Master Angler entries are fish that met the program’s minimum size and were registered by the angler — they show what this lake has produced, not what a day here will produce. A catch on record is history, not a species listing: “Fish you might catch” lists only species with current evidence. Source: Michigan DNR Master Angler data.
